Radio TV Srbija

Almost every home has a television today. It offers programmes from a
number of available channels and is very simple to use. The Cable TV
(CATV) makes it possible to choose programmes from large number of
channels. Then became video rental business in combination with a video
recorder, which provides customers to select movies when they will.
This service may be called video on demand.

Nowadays Video-on-Demand (VoD) includes much wider services and
opportunities. Today s technology allows telecommunication network
operators to offer such services as home shopping, games, and movies
on demand. These services should have a competitive pri ce comparing
to the video rental, and customers do not need to travel for the
services. These possibilit ies have been reached by the development of
the telecommunication and electronic industry. The capacity of a hard
disk has doubled almost every year at near-constant cost. The useful
compression ratio for video has been increased considerably,
MPEG-format ted video can be transported at a bit rate of few
Mbit/s. The digital signal processing techniques permit the transport
of a few Mbit/s over existing copper wires for a distance of a few
kilometres. Finally, Asynchronous Transfer Mode (ATM) systems allow
the switching of any reasonable bit rate to a single or multiple
customers among a large number of connected customers. However, today
s transmission bandwidth is large only downstream towards the customer
with narrow upstream bandwidth. But upstream bandwidth will also
become wider in the future, then interactivity between the customer
and the service provider will increase.

This new technology is being developed all the time, because
Video-on-Demand has so many different applications to offer to the
custo mers and economical possibilities have been seen. Many
companies, organisations and universities are developing products and
standards. Both cable TV and telephone operators invest to their
networks and have some trials in Video-on-Demand. To finance the
required investments, higher consumer volumes must be reached from
residential side instead of business side that is running ahead in the
development of technology. The battle is hard, and it is getting
harder all the time. So some companies have establis hed business
relationships to get their knowledge and resources together. In
addition, they may avoid some regulation restrictions before
telecommunication markets are opened to everyone.
